    <p>there must be someone out there who can spot my error! I'm parsing an xml feed and running through a loop to get certain items on the page:</p> <pre><code>www.highlandradio.com/feed/ </code></pre> <p>I am encountering an error on the line where I am setting the variable mp3Test. All I want to do is to set it equal to the url attribute of the enclosure tag (if it exists). This is why I am including the test to check if each item has an enclosure tag, if it does I am setting it to be equal to the url tag but if it doesn't I am setting it to be equal to 'null.mp3' for now. When running through the loop I am getting the correct numbers for a certain amount and then on some iterations of the loop, i crashes. I am using titanium and so am not getting any proper error messages. It simply highlights the line where I set up mp3Test and says to debug the current instruction pointer. I'm going crazy with this. Please help. </p> <pre><code>var url="http://www.highlandradio.com/feed/"; var xhr = Titanium.Network.createHTTPClient(); xhr.onload = function() { // Data is returned from the blog, start parsing var doc = this.responseXML.documentElement; // begin looping through blog posts var items = doc.getElementsByTagName("item"); var enclosure = doc.getElementsByTagName("enclosure"); console.log("NEWEST Enclosure Length -----------"+enclosure.length); for (var i = 0; i &lt; items.length; i++) { var itemsEnclosureLength=items.item(i).getElementsByTagName("enclosure").length; var itemsEnclosureExists=items.item(i).getElementsByTagName("enclosure"); console.log("EXISTs ----------------------------------"+ itemsEnclosureExists); console.log("Newest ENCLOSURE LENGTH ---------------------- [ "+i+ " ]" + itemsEnclosureLength); var str=items.item(i).getElementsByTagName("content:encoded").item(0).text; console.log("STRING TEST "+ str); var patt1=/([a-z\-_0-9\/\:\.]*\.(jpg|jpeg|png|gif))/i; var urlMatch = str.match(patt1); console.log("MATCHES TESTER -----------------------------------" + typeof urlMatch); data.push({ title: items.item(i).getElementsByTagName("title").item(0).text, leftImage: str.match(patt1) !== null ? str.match(patt1)[0] : 'image_news.png', dataToPass: items.item(i).getElementsByTagName("description").item(0).text, mp3Test: itemsEnclosureLength &gt; 0 ? items.item(i).getElementsByTagName("enclosure").item(i).getAttribute("url"):'NULL.MP3' }); console.log("Check this --------------------------"+ mp3Test); } </code></pre> <p><strong>BUMP2</strong></p>

    1. CO`items.item(i)` should be `items[i]`, shouldn't it?

    2. CO@Barmar no. Not with Titanium. items.item(i) is working fine for all other tags. If I comment out the line with mp3Test, it will run. There's something I'm missing :(

    3. CO@Barmar It can be, but technically, `.item()` is a real, valid method: https://developer.mozilla.org/en-US/docs/Web/API/HTMLCollection#Methods . I like `[i]` better though

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
